United States Patent CURVED TENSION CLIP AN'D ATTACHABLE CURVED HANDLEHAIR 'IRIMMER Nathan S. Brody, Los Angeles, Calif.

Application October 3, 1955, Serial No. 538,178 3 Claims. (Cl. 30-30) Myinvention relates to an improved hair trimmer which is provided with acurved spring tension clip and an attachable curved handle. Said clipemploys in its assembly a small, curved comb and, additionally, a doubleedge safety-razor blade, said latter being thin and resilient and havinga central longitudinal perforation like most of the conventional doubleedge safety razor blades. One of the outstanding features of myinvention is, that no springs are employed to provide the clampingtension to hold said safety-razor blades in their place whetrinsertedinto said clip; instead, the clamping tension is provided by theresiliency of said safety-razor blades themselves. A second outstandingfeature of my invention is had in the curved condition of bottomsections of two clamping parts comprising said spring tension clip of myinvention, and also in the curvature of said attachable handle, both ofwhich correspond with the curvatures of the back of the head, nape andneck and thus make for better and more efficient application of theassembled clip hair trimmer of my invention. A third novel feature of myinvention is had in the attachable handle which is, alternatively,attached to either side of. said assembled clip; thus said latter neednot be readjusted when shifted from one side of the back of the head tothe other side.

In the accompanying drawings Fig. 1 shows a face view of my inventionfully assembled. Fig. 2 shows the reverse side of said tension clip byitself, presenting a perspective view of same. Fig. 3 shows the middle,bottom clamping section of the upper part of said clip on its innerside; here to, it can be seen how said safetyrazor blade is inserted andclampingly held by said straight side of said rigid tooth centrallypositioned between said two severed sides of said longer clamping partof said clip. Fig. 4 shows a face view section of the stamped out sheetof metal of said upper clip part presenting an enlarged view of saidrigid tooth prior to the forming of same into a vertical position. Fig.5 shows said rigid tooth in the process of being formed. Fig. 6 shows aview of my invention as one would see it on looking down from above Fig.1, thus showing the curvatures of said blade clamping parts and of saidhandle.

To present the details of my invention: in Fig. 1, 1 indicates the upperclamping part of said spring tension clip; 2 indicates the bottomclamping part of said clip; 3, 3 indicate the two groups of oppositelypositioned arched bands, pierced and formed in the horizontal midsection of said upper part of said clip; said two groups of raised,arched bands are to receive, alternatively, said attachable handle atthe one side or at the other side of said assembled clip hair trimmerfor the operating of same; said two groups of bands begin with a largersemi circle and taper to a smaller arched band thus providing a snuggrip on the tapering tongue of said handle; 4 indicates the holes inback of or underneath said raised, arched bands; 5, 5 indicate the twocurved and severed 2,81%,953 Patented Oct. 29, 1957 bottom sectionsflanking said centrally extending rigid tooth not shown here; 6indicates the upper and attached section of said tooth where it had beenformed; 7 indicates the longer cut out, while 8 indicates the shortercut out of said mid-section at the two sides of said tooth extendingbehind said razor blade; 9, 9 indicate the hinge sections of said bottomclamping part of said clip which receive said hinge sections of saidupper part of said clip; 10 indicates the riveted ends of a rod whichholds the several parts comprising said spring tension clip, including acoil spring, together in their mechanical assembly; 11 indicates theupper, solid side of said curved combwhich is especially made to fitsaid curved clip of my invention; 12 indicates the side guard teeth ofsaid comb, while 13 indicates the teeth of said comb; 14 indicates theinwardly projecting prongs, as shown in Fig. 2; 15 indicates thesafety-razor blade; 16 indicates the perforation at the center of saidblade where it is clampingly held, after being inserted as shown in Fig.3; 17 indicates the curved attachable handle as it would be held at theone side of the back of the head and affording the operator anunobstructed view at the opposite side of said head or neck when makinguse of two mirrors, the one to look into and having the other mirror atthe side or at the back of the head; 18 indicates the larger end of saidhandle, while 19 indicates the narrow portion of said curved handle atthe attachable end; 20 indicates the shoulder at this end, while 21indicates the tapered tongue extending from this end of said handle,said latter being received, alternatively, and held by said two groupsof arched and tapering band-loops as shown; 22, 22 indicate two cut outsections showing the depth of said han dle. In Fig. 2, 29-A indicatesthe elongated, rigid tooth itself; 23 indicates the stem end of the coilspring at this one side of said'clip; 24 indicates the coil spring ofsaid clip, in the cut out; 25 indicates the cut out in said inwardlycurved bottom midcenter of said bottom part of said clip, thus alsosevering it into two sections, this condition being needed to receivesaid upper vertically extending section of said rigid tooth and thus topermit the closing of said clip when said latter is not assembled asshown in this Figure 2; here too it can be seen that said severed andinverted bottom edge 26, 26 is arched inwardly to fit correspondingly,with the outwardly curvedupper part of said clip; 14, 14 shows the twoinwardly formed prongs extending at the sides of said upper clampingpart of said clip, said prongs serving to engage the end perforations ofsaid double edged safety-razor blades thus checking their side movementswhen said blades are used in the assembly of said clip; 27 indicates thearched edge of said tooth while 28 indicates the straight edge of saidtooth, said arched side being positioned between teeth of said comb tokeep said clip in a straight position when moved up or down upon saidcomb for longer or shorter hair trimming; here too, in this figureshould be particularly noticed the dissimilarity in the length of thetwo clamping parts of said clip of my invention. In Fig. 3, 29 indicatesin the enlarged assembled section of said upper part of said clip thepointed end of said rigid tooth and showing that it terminates beyondsaid edge of said razor blade when fully inserted; here too can be seenthe procedure of inserting said blades: thus the point of said tooth 29,being inserted through the midcenter perforation of said blade 16, 16,makes its way easily between blade sections 15-A and 15-B. In Fig. 4, 30shows the enlarged rigid tooth in its flat stamped, or blanked conditionbefore it is formed. In Fig. 5, 31 shows said tooth in the process ofbeing formed into a vertical and somewhat lower position. Fig. 6 shows aview of my invention as one would see it on looking down from above Fig.1, thus showing the curvatures of said blade clamping parts and of saidhandle.

Having described my invention I claim:
